About

Building is cheap now. Knowing what to build isn't.

Your teams can ship faster than ever, so the costly mistake is shipping the wrong thing. I run continuous discovery: talking to your customers every week, mapping where the real opportunities are and testing the riskiest assumptions on value, usability, feasibility and viability before engineering commits. Over ten years as a developer, UX lead and product manager, now with AI doing the heavy lifting, means I take an idea from interview to working prototype myself. You only invest where the evidence is, and every bet is tied to a business outcome you can measure.

What I do

AI/Automation

Hours back across your teams, without adding headcount. Discovery first: I find the manual work that costs the most and the outcome removing it should move. Then automations and AI agents that run reliably in production, with evals that define what good looks like.

Product

Outcomes, not output. Continuous discovery with customers every week, opportunity mapping and fast assumption tests, so your teams commit to the bets that move revenue and retention instead of a feature list.

Design

Products customers and employees adopt on the first try. Interviews, prototypes and usability tests early in discovery catch the friction before it costs engineering time, and design systems built in Claude keep large teams fast and consistent.

Code

Build to learn, then build to earn. Working prototypes in days with Claude Code put real evidence in front of customers and stakeholders. What proves its value goes to production in TypeScript, React, Next.js, Node, Three.js or Swift, inside your existing stack.

Growth

More qualified demand, measured in pipeline. SEO and GEO so Google and AI assistants recommend you, and email that turns that traffic into customers. The technical side of growth, run as experiments with clear outcomes.

Contact

Tell me what's not working. I'll help you define the outcome that matters and map how we get there: what to test first, what it takes and how soon you'll see it move. One email, no sales process.
